Superstar Gwen Stefani stripped down to a tiny bikini top when she hit the beach with her adorable family over the weekend and RadarOnline.com has all the photos of all the bunch having fun in the sun.

Holding hands with her gorgeous husband Gavin Rossdale, Gwen showed off her taut abs with her black bikini top and low riding skirt while their boys played in the sand.

The rocking Hollywood family knows how to beat the heat, by cooling-off in the waves of the Pacific Ocean. And their two little boys, Kingston and Zuma, had a blast building a sand castle on the beach.

Gwen, 41, later covered-up in a Marilyn Monroe t-shirt and the resemblance between the two blonde bombshells was uncanny!
